VX Sagittarii, also known as HIP 88838, is red hypergiant star with a diameter pulsating between 1,120 and 1,940 times greater than the Sun, a luminosity between 110,000 and 263,000 times that of the sun, and a very cool temperature between 3,200 and 3,400 degrees Kelvin. The star has a pulsation period of 732 days and is located 1.5 kiloparsecs away from the Earth. Older studies frequently calculated much higher luminosities.
